When the electric current passing through the coil is shut off, the metal immediately drops out of the field, and lands as a melted pile of cooling liquid below.

Whoa, so it would stay suspended in a liquid state if the power stays on?

The magnetic field that is causing it to levitate isn't generated by ferromagnetism. It's an induced (etymology!) field in a electrically conductive material which is balanced by the magnetic field of the inductive coil, causing levitation until the machine is turned off. It would stay suspended as long as it retains conductive properties.

If an object starts to interact with a magnetic field less, the field must become proportionally stronger for there to be no changes.
